Venation Parallel: Izici isakhiwo izitshalo

Parallel venation amahlamvu yendalo njalo ngokwanele futhi isici esibalulekile saleso sihlahla ngezigaba. Kwamanye eziphilayo, kuba ejwayelekile futhi yiziphi izici zayo, sizoxoxa sihloko namuhla yethu.

Kuyini venation

Uhlu - isitho ebaluleke kakhulu isitshalo, enza imisebenzi ebalulekile. Ngokuyinhloko Kugcwaliseka inqubo transpiration kanye photosynthesis. Izinto okuyinto akhiwa ngesikhathi esifanayo, udlulele ishidi indlela ekhethekile. Kuyinto iqoqo izakhi Indwangu conductive noma, ngaphezulu nje, emithanjeni yegazi. Bona zingahlelwa ngeluhlelo lolwehlukile. Ziya ngokuya indawo yabo futhi ngokuthi veining.

izinhlobo venation

Kunezinhlobo ezintathu oyinhloko venation. Lokhu anezikhala, arc futhi ngokulinganisa. Futhi ngokwemvelo kukhona ubuhlobo ocacile phakathi ukuma iqabunga lomshini bese uhlobo indawo emithanjeni. Cabanga ngesibonelo lokhu kwencika kwi izitshalo ezimbalwa ezivamile. Ngokwesibonelo, palchastye amahlamvu e-maple baye reticulate venation, lapho lenqwaba main semithambo fibre ivelele ngokucacile. Dedani kubangelwa oda wesibili nowesithathu. Ilungiselelo elifanayo esivamile ngoba cherry, peach, rose, soy, ubhontshisi, amazambane, utamatisi, iklabishi nezinye dicots eziningi. Ngo amaqabunga komugqa akha isakhiwo ezahlukene ohlelweni conduction. Uma umthambo main akuyona esabiwe, kanye eduze sisuka base ishidi kusuka kwelinye iphuzu we lwesikhathi, bese uxhumekile onesiqongo, lesi sibonelo yohlobo yesibili. Kuyinto ejwayelekile, isibonelo, umnduze kwesigodi ukhova. veining Parallel futhi kwenzeka amahlamvu komugqa.

Parallel venation ishidi

Kakade kusukela igama kuyacaca ukuthi lihambe ngemithambo amaqabunga ahlelwe parallel nomunye. Bona ukunweba kusukwa plate ukuhamba ngayo. venation Parallel kuyisici sobuntu monocots. Lezi zihlanganisa amalungu amaningi omkhaya okusanhlamvu, onion lily. Emaphethelweni izindwani leaf kungukuthi ahlahlelwe, futhi uqonde thwi, okwenza kube lula zifana ilungiselelo emithanjeni.

Izitshalo nge venation parallel

Futhi venation parallel ngoba monocot isici kuba khona umbungu nomunye cotyledon, fibrous uhlelo impande, ukuntuleka izicubu cambial e isiqu, amacembe lwesitho sangasese sowesifazane. Phakathi le amayunithi utshani ehlelekile ezivamile, okungenani - nezihlahla.

Okubaluleke kakhulu kwezomnotho phakathi kwabo kukhona utshani noma bluegrass izitshalo. Ukolweni, rye, ibhali, irayisi - konke okusanhlamvu ezaziwayo. Couch utshani, Kentucky bluegrass, uThimothewu, brome ayisibonelo asemaqeleni izitshalo zazo ngokuphelele bazivumelanisa imibandela kancane iqhwa obubandayo olushisayo ezomile. Phakathi okusanhlamvu, futhi eziningi ezibalulekile ifolishi izitshalo.

Ngo lily, okuyizinto izitshalo ezibalulekile zokuhlobisa noju, kukhona abamele veining ngokulinganisa. Banesimiso ukuguqulwa ebalulekile Ukuphunyuka komhlaba - onion. Ukusebenzisa idatha wakhe vegetatively okusakazwa izitshalo futhi idluliselwe nesomiso nezikhathi umnkantsha.

Njengoba ligcwele kuzo endalweni bese anyanisi. Ngokuvamile, zikhula ku izimfunda kanye ihlathi ezivulekile. Ngenxa ama, bayakwazi khona nemibandela emaqeleni, amathafa kanye ezingwadule.

Ngakho zifana veining ejwayelekile abamele ikilasi ka monocots. Lolu hlobo lwe-ilungiselelo ishidi izakhi conductive emelelwa izinyanda fibrovascular zazo wahlela kanye plate amahlamvu komugqa.
